Every grower struggles with the perfect cure.
Advice for large scale growers is different than what the process will be for home growers and medical patients growing only for themselves.
I've come to the same conclusions as the OP, but I have ideas about why it works so well for me.
Laziness ruins people's cure, or doing too much at one time.
If you want the perfect cure, which will preserve your carefully crafted Cannabis for months while still getting better and more refined, you cannot give up the last couple weeks of the process.
I've tried all sorts of methods, used all sorts of equipment, but for the buds I keep for myself it's a slow process of stabilizing ph in the plant material, then bleeding off the excess bit by bit over a few weeks. Nothing has proven as useful and as accurate as Mason jars, IMO. They come in several sizes and they are ...... airtight. So many bins, boxes, and jars are not as airtight as they advertise.
The burping process is the skill most people need to acquire.
The longer the process takes, the better the final product. (genetics being the limiting factor)
I was lazy. I let herb get too dry, I let it get too moist. In each case the cure was not up to par at the end. Either it would begin to dry out after a while, or it would slump and lost its taste and flavor.
I am of the opinion that there is no convenient and easy replacement for checking the jars as frequently as they require, to keep the plant material perfectly in the "safe" zone.
You cannot simply decide "I will check them every 6 hours!" and think everything will be just fine.
Practice will inform you when to move from dry to cure, and how frequently to check a jar.
The goal is to maintain the proper ph levels at all time.
When the target ph is reached and seems stabilized, THEN is the time for humidity packs, to maintain over the long term. I prefer to target about 58% or so. the 62% are too wet, and the 55% Integra are too dry. Either seems to make the herb want to powder after a period. Keep it around 58% and it stays pliable and fresh for the long term, has been my experience. This could be because of my ambient humidity due to locality, and is meant as example.
The OP is spot on. It was a gem dropped at your feet.
Take the time, pay attention, devote the time, and serve up your friends some 12 month cure that smokes so smooth they get their feelings hurt when you won't sell them any.
The Devil is in the details.
This is just my personal opinion, and is meant as agreement with the OP only.
